I'm not sure that I understand very well how the state of a group can
be measured. For a port I can understand that we look if the link
connected to this port is up or down but I don't see how it can be
done for a group?

Ok thanks, and when do you expect to release the patches?
If I understood well if I push these rules:
$ curl -X POST -d '{
"dpid": 1,
"type": "FF",
"group_id": 1,
"buckets": [
{
"watch_port": 2,
"actions": [
{
"type": "OUTPUT",
"port": 2
}
]
}
{
"watch_port": 3,
"actions": [
{
"type": "OUTPUT",
"port": 3
}
]
}
]
}' http://localhost:8080/stats/groupentry/add
$ curl -X POST -d '{
"dpid": 1,
"match":{
"nw_dst": "11.0.0.2",
"eth_type": 2048
},
"actions":[
{
"type":"GROUP",
"group_id": 1
}
]
}' http://localhost:8080/stats/flowentry/add
the switch 1 will send the packet that have for destination 11.0.0.2
out through the port 2 if the link connected to port 2 is working and
out through the port 3 (if the link connected to port 2 is not working
and the one connected to port 3 is working). Right?
Thanks,
Best,
Clément
